wm_adsp originally provided firmware loading on some audio DSP and was implemented as an ASoC codec driver. However, the firmware loading now covers a wider range of DSP cores and peripherals containing them, beyond just audio. So it needs to be available to non-audio drivers. All the core firmware loading support has been moved into a new driver cs_dsp, leaving only the ASoC-specific parts in wm_adsp.

drm-misc-next for v5.15-rc1: UAPI Changes: - Remove sysfs stats for dma-buf attachments, as it causes a performance regression. Previous merge is not in a rc kernel yet, so no userspace regression possible. Cross-subsystem Changes: - Sanitize user input in kyro's viewport ioctl. - Use refcount_t in fb_info->count - Assorted fixes to dma-buf. - Extend x86 efifb handling to all archs. - Fix neofb divide by 0. - Document corpro,gm7123 bridge dt bindings. Core Changes: - Slightly rework drm master handling. - Cleanup vgaarb handling. - Assorted fixes. Driver Changes: - Add support for ws2401 panel. - Assorted fixes to stm, ast, bochs. - Demidlayer ingenic irq.

The register_gop_device() function registers an "efi-framebuffer" platform
device to match against the efifb driver, to have an early framebuffer for
EFI platforms.
But there is already support to do exactly the same by the Generic System
Framebuffers (sysfb) driver. This used to be only for X86 but it has been
moved to drivers/firmware and could be reused by other architectures.
Also, besides supporting registering an "efi-framebuffer", this driver can
register a "simple-framebuffer" allowing to use the siple{fb,drm} drivers
on non-X86 EFI platforms. For example, on aarch64 these drivers can only
be used with DT and doesn't have code to register a "simple-frambuffer"
platform device when booting with EFI.
For these reasons, let's remove the register_gop_device() duplicated code
and instead move the platform specific logic that's there to sysfb driver.

The x86 architecture has generic support to register a system framebuffer
platform device. It either registers a "simple-framebuffer" if the config
option CONFIG_X86_SYSFB is enabled, or a legacy VGA/VBE/EFI FB device.
But the code is generic enough to be reused by other architectures and can
be moved out of the arch/x86 directory.
This will allow to also support the simple{fb,drm} drivers on non-x86 EFI
platforms, such as aarch64 where these drivers are only supported with DT.

Allow the qcom_scm driver to be loadable as a permenent module. This still uses the "depends on QCOM_SCM || !QCOM_SCM" bit to ensure that drivers that call into the qcom_scm driver are also built as modules. While not ideal in some cases its the only safe way I can find to avoid build errors without having those drivers select QCOM_SCM and have to force it on (as QCOM_SCM=n can be valid for those drivers). Reviving this now that Saravana's fw_devlink defaults to on, which should avoid loading troubles seen before.

The Arm FF for Armv8-A specification has concept of endpoints or partitions. In the Normal world, a partition could be a VM when the Virtualization extension is enabled or the kernel itself. In order to handle multiple partitions, we can create a FFA device for each such partition on a dedicated FFA bus. Similarly, different drivers requiring FFA transport can be registered on the same bus. We can match the device and drivers using UUID. This is mostly for the in-kernel users with FFA drivers.

In order to add newer SMCCC v1.1+ functionality and to avoid cluttering PSCI firmware driver with SMCCC bits, let us move the SMCCC specific details under drivers/firmware/smccc/smccc.c We can also drop conduit and smccc_version from psci_operations structure as SMCCC was the sole user and now it maintains those. No functionality change in this patch though.

Dynamically support SMCCCC and legacy conventions by detecting which convention to use at runtime. qcom_scm_call_atomic and qcom_scm_call can then be moved in qcom_scm.c and use underlying convention backend as appropriate. Thus, rename qcom_scm-64,-32 to reflect that they are backends for -smc and -legacy, respectively. Also add support for making SCM calls earlier than when SCM driver probes to support use cases such as qcom_scm_set_cold_boot_addr. Support is added by lazily initializing the convention and guarding the query with a spin lock. The limitation of these early SCM calls is that they cannot use DMA, as in the case of >4 arguments for SMC convention and any non-atomic call for legacy convention.
